Abstract
A process for separation of carbon dioxide and sulfur containing compounds from a gas stream including the step of feeding the liquid physical solvent absorbent containing dissolved carbon dioxide and sulfur containing gases into the central region of a fractionating column and introducing liquid physical solvent absorbent substantially free from dissolved gases in the upper region of the fractionating column while maintaining the fractionating column under conditions of temperature and pressure whereby at least one of the undesired gases passes from the upper region of the column and the liquid physical solvent absorbent containing remaining dissolved gases passes from the lower region and introduction of feed to the fractionating column is at a location of the column at approximately the position wherein the column contents composition under operating conditions is the same as the feed composition. The process provides for purification of gas streams under pressurized conditions and regeneration of the physical absorbent separates fuel gases, CO.sub.2 and sulfur containing compounds.
